I am proposing that an original poster for a thread be able to select a character or word count cap for replies.
I see the value of limiting reply length because it creates a more reader friendly thread. A long reply can easily be skipped or skimmed and any points made might be ignored or taken out of context.
Additionally, people who truly want their view to be understood will have to choose their wording more carefully. Many times, I have had to reread long texts multiple times to understand the intent of the post.
This might not be feasible for this forum but it is worth asking for.
